Form types extensions doesn't work

[zquintana]

Last part of the documentation about adding form types, doesn't seem to work. I can't see were that is implemented in the code here.

I'm having the same issue on the latest version of this package.

Worked around this by using the following in a provider, also allows usage of the Doctrine EntityType.

// In service provider register method

$this->app->extend('form.extensions', function($extensions, $app){
   $extensions[] = app(DoctrineOrmExtension::class);

   return $extensions;
});

Down side to this approach is you need to create an actual extension but in theory you can have one extension and keep adding to it.
